I am doing a project on which way is the best way to trigger a SCR, and I need some bibliography sources to support my hypothesis so please tell me which one is the best. Also, I need to learn how to build a squirrel cage induction motor.

dear......., first read the books of power electronics to make u'r concepts clear then u can use the site www.alldatasheets.com to get the data for particular scr like . triggering voltage ,current ,time of triggering,etc
